To all whom it may concern:

Be it known that I, EMIL Sorriinnn, a citizen of the SwissConfederation, residing at 86 Steinwiesstrasse, Zurich, Switzerland,have invented new and useful Improvements in Brackets for Staging andScaffolding, of which the following is a specification.

The present invention relates to brackets adapted to be used for stagingand scaffoldmg.

An object of the invention is to provide means which may be readilyfitted to and detached from any building for instance for repairingpurposes, painting or the like.

A further object of the invention is to provide suitable means to makethe attachment of brackets perfectly secure to prevent any accident tothe men using the scaffold supported by the brackets.

In the drawing Figure 1 shows a bracket fixed to the wall of a building.Fig. 2 shows a holding socket adapted to be fixed in a wall. Fig. 3 is afront view of the socket shown in Fig. 2. Fig. 4 shows another form of asocket and Fig. 5 shows a cover for the socket, in front and side views.Fig. 6 is a front view of a third form of a socket and Fig. 7 is a sideview thereof.

Similar letters refer to similar parts throughout the specification.

To form a platform suitable for making repairs on the outside of thewalls of the buildings, brackets are used. On the bars 0, of thebrackets boards n are placed which serve as a stand for the operator.The upper ends of the uprights 0 may be connected by a chain, bar or thelike to serve as a safeguard. The bracket consists of a bar 0 bent atright angles at 0 The free end of the horizontal portion of bar 0, isround in cross section and is provided with two projections Qdiametrally opposite each other. On the horizontal portion of bar 0, oneend of a bar r is rigidly fixed, the other end of which is slightly bentso as to run parallel to the free end of bar 0. To stiffen the bracket,truss s is provided rigidly fixed to bar 0 and to bar r. The free end ofbar 0 lies in the opening of a socket u fixed in the wall. The socketSpecification of Letters Patent.

u is closed at its front end by a disk 24 which may be flush with thewall of the building. In said disk is a circular opening having tworecesses a arranged opposite each other. The dimensions of the openingin said disk are such that the free end of the bar 0 may be easilyinserted. The recesses a are situated in a vertical line when the socketis correctly placed in the wall and the bracket has to be turned whenremoved from the position shown in Fig. 1. The free end r of the bar ris inserted (Fig. 1) in a socket '0 (Fig. 4) having a straightcylindrical bore to allow the insertion of the free ends of the bars 0and r. The openings of the socket-s u and o are made wide enough to givesufficient play. To cover the openings of the sockets 4), when not inuse, covers to may be employed which may be placed in a recess of thesocket and which are held by lugs w engaging a groove of the socket. Toallow insertion of the lugs w the outwall of the groove is recessed. Thesocket for the end of bar 0 may be made as shown in Figs. 6 and 7. Thesocket t is made of a piece of iron of rectangular cross section, thefront end having the opening for the end of bar 0. The sockets t and '0are fixed in the walls of the building at regular distances apart, sothat a stage may be erected for any part of the wall of a building.

I wish to point out that various changes in the form and dimensions ofthe parts may be made without departing from the spirit of theinvention.

What I claim is- The combination with an exterior wall, of a scaffoldingsocket therein and substantially flush with the exterior face of saidwall and provided with an opening having substantially verticallydisposed extensions, a scaffolding bracket member having horizontallydisposed projections adapted to be inserted into said sockets and turnedto an upright position to dispose its projections out of registry withthe extensions of the opening in said socket, the portion of the bracketmember entering said socket being loosely mounted thereln wherebyswinging movement is permitted said bracket member, to sustain the samein a horizontal position, 10 a socket located in the Wall beneath thefirst substantially as described.

mentioned socket, and a bar connected to In testimony whereof I afiix mysignature said bracket adjacent its outler end and in presence of tWowitnesses.
